Mean Creek (2005)

Set in a small Oregon town where secrets are hard to keep and lies even harder, "Mean Creek" flows with the simple elegance of truth and consequences as it follows a crisis in the lives of its teen characters. The journey begins as a plot for a playful payback on a local troublemaker; a ragtag group of troubled-and-not teenagers set out on a boat trip to celebrate the supposed birthday of a member in their group. Soon enough, cracks in the crew form when some of the teens have second thoughts about what they have come there to do.
